refactor(editor): complete state machine and services migration

BREAKING CHANGE: MemoEditor internal architecture completely refactored

## Summary

Refactored MemoEditor from hooks-based state management to a three-layer
architecture (Presentation → State → Services) using useReducer pattern.

## Changes

### Architecture
- **State Layer** (5 new files): types, actions, reducer, context, barrel export
- **Service Layer** (6 new files): error, validation, upload, cache, memo services + barrel
- **Component Layer** (3 new files): EditorToolbar, EditorContent, EditorMetadata
- **Simplified Hooks** (3 new files): useMemoInit, useAutoSave, useKeyboard

### Code Reduction
- Main component: ~380 lines → ~140 lines (-63%)
- Hooks removed: 5 old hooks (useMemoEditorState, useMemoSave, etc.)
- Total lines removed: 508 lines of old code
- Utility hooks preserved: 8 hooks still in use (useLocation, useDragAndDrop, etc.)

### Improvements
-  Predictable state transitions with useReducer
-  Testable business logic in pure service functions
-  Cleaner component code (presentation only)
-  Better separation of concerns
-  Type-safe actions with discriminated unions
-  Centralized error handling

## Statistics
- Files changed: 26
- Commits created: 25 (squashed into 1)
- New files: 17
- Removed files: 5
- TypeScript errors: 0
- Lint errors: 0

## Testing
Manual testing required for:
- Editor functionality (create, edit, save)
- Drag and drop
- Focus mode
- Keyboard shortcuts (Cmd/Ctrl + Enter)
- Auto-save to localStorage

# MemoEditor Architecture
## Overview
MemoEditor uses a three-layer architecture for better separation of concerns and testability.
## Architecture
```
┌─────────────────────────────────────────┐
│ Presentation Layer (Components) │
│ - EditorToolbar, EditorContent, etc. │
└─────────────────┬───────────────────────┘
┌─────────────────▼───────────────────────┐
│ State Layer (Reducer + Context) │
│ - state/, useEditorContext() │
└─────────────────┬───────────────────────┘
┌─────────────────▼───────────────────────┐
│ Service Layer (Business Logic) │
│ - services/ (pure functions) │
└─────────────────────────────────────────┘
```
## Directory Structure
```
MemoEditor/
├── state/ # State management (reducer, actions, context)
├── services/ # Business logic (pure functions)
├── components/ # UI components
├── hooks/ # React hooks (utilities)
├── Editor/ # Core editor component
├── Toolbar/ # Toolbar components
├── constants.ts
└── types/
```
## Key Concepts
### State Management
Uses `useReducer` + Context for predictable state transitions. All state changes go through action creators.
### Services
Pure TypeScript functions containing business logic. No React hooks, easy to test.
### Components
Thin presentation components that dispatch actions and render UI.
## Usage
```typescript
import MemoEditor from "@/components/MemoEditor";
<MemoEditor
memoName="memos/123"
onConfirm={(name) => console.log('Saved:', name)}
onCancel={() => console.log('Cancelled')}
/>
```
## Testing
Services are pure functions - easy to unit test without React.
```typescript
const state = mockEditorState();
const result = await memoService.save(state, { memoName: 'memos/123' });
```
